SYNTHESIS AND PHOTOCATALYTIC CO2 REDUCTION OF METALLOPORPHYRIN AND H5[PMo10V2O40]•34.5H2O COMPOSITE CATALYST

Inspired by the structural motifs of chlorophyll, a series of bio-inspired Z-scheme heterojunction photocatalysts y PMo 10 V 2 /CoTPyP were constructed by integrating metalloporphyrin CoTPyP with H 5 [PMo 10 V 2 O 40 ]·34.5H 2 O. The optimized 0.1PMo 10 V 2 /CoTPyP heterojunction exhibits remarkable photocatalytic CO 2 reduction performance, achieving a CO production rate of 316.88 μmol·g −1 ·h −1 , which is 3.7 times and 5.9 times higher than those of CoTPyP and H 2 TPyP, respectively. Systematic characterization confirms that the Z-scheme electron transfer mechanism effectively promotes charge separation while maintaining high redox capability. This work demonstrates the feasibility of mimicking natural photosynthesis through rational material design and provides valuable insights for developing efficient artificial photosynthetic systems.
